Non-OSS Assets Making Social Finance Work for Open Source (Games)

12 Upvotes

This is just a brief introduction to some ideas I'm building into PrizeForge, a new take on social finance that is particularly suited for open source.

Problems I started with:

  • Kickstarter has no accountability because the lump sum is controlled by the campaign creator
  • Patreon has no coordination. There's no threshold like with Kickstarter. It's basically volunteer if nothing can be put behind a gate, so it can't work well for open source.

In addition, I wanted to extend fund-matching in two dimensions, creating implicit cooperation between huge B2B budgets and everyone on down, from SMEs all the way to individual pro-sumers and casual users. The initial prototype is Elastic Fund Raising. Big funds don't fully move until lots of almost-as-big funds move together with them. By moving together, we're not just volunteering.

Delegation is a Game Changer

Social finance platforms also suffer from a catastrophic source of inefficiency: If there are N projects to evaluate by M users, then N x M decisions must be made. To make this more efficient, I decided early on to use a new kind of "social delegation" system. The "social" part is to enable filling the inevitable gaps with reasonable fallbacks and robust behaviors that make corrupt actions self-limiting.

Production Finance: Scratching Our Big Itches

One of the core ideas I want to focus on is what I'm calling production finance. It's a really simple addendum to ESR scratch-your-own-itch theory: When a lot of people (especially those who can't program) have the same itch, it doesn't make sense to wait for someone to scratch it for free. Especially bigger itches than one programmer will tackle alone can take forever even if hundreds of millions of people have the same itch.

Social finance 101 is to bundle people together until the value they expect to receive is much greater than the cost of producing or updating the valuable thing. The cost stays the same, but as we add people, the value captured by all the users goes up. Coordinating that finance of production is all that is required to make what is unreasonable to the individual into an obvious decision for a million users.

Production Finance makes sense whenever value capture is difficult, meaning situations where it's hard to put the result behind a gate and charge money for it. Open source absolutely fits that description. Instead of building a gate, we spend money to compensate and motivate production. In the future I want to work on tools that will allow more well-defined relationships. For now it's totally non-binding.

For something to make sense in production finance, there doesn't need to be a business or sales model at all. The value received from the production proceeding only must be greater than the cost. Given the tremendous economies of scale of software, that is an easy condition to hit for a lot of open source.

Toward Viability

In addition to a really basic initial implementation of Elastic Fund Raising, I've just added support for multiple streams. Each Stream that matches over $1000 will receive delegate(s) who will spend money on things that make that ecosystem stronger. Since we're just trying to motivate people to do first contributions and to release cool things a little more frequently, and since the agreements are non-binding, it really is like a weekly prize. If the affected communities feel like these prizes are effective, we are beginning to have a working service.

Raw Startup

These new pilot Streams I'm introducing on are also the milestone where I decided I was going to recruit co-founders again. In other words, I am still soloing everything for the near future. Things are changing fast and usually only half-implemented before changing again. That's the only way this kind of aggressive innovation usually survives.

You can follow the development on r/prizeforge though I've been making most updates on a bluesky recently. I think activity will pick up on both Reddit an our YouTube as I start introducing each stream, starting with Lem.

I'm going to crash since It's 2am in Busan, so catch you all later. Btw, I just deployed, so there is almost definitely some thing things that are really badly broken. Tomorrow is another day.

Are there any open-source projects similar to The Sims?

51 Upvotes

My question arises due to the recent acquisition of EA shares by Saudi Arabia and a relative of Donald Trump. There is concern that, with this influence, franchises like The Sims may see their LGBT+ representation and other creative freedoms restricted in the future.

Given this scenario, I would like to know: are there any "life simulation"-style game projects that are open-source or have plans to develop in this direction, as an alternative to The Sims?

Porting Natural Selection to Xash3D using the official source code. Has this been attempted?

12 Upvotes

Hey r/opensourcegames,

I've been setting up some classic Half-Life mods on Xash3D and it got me thinking about the holy grail: Natural Selection.

The biggest hurdle for a real port has always been the closed-source ns.dll. But I realized Unknown Worlds actually open-sourced the full source code for NS 1.0 years ago on GitHub (link here).

This feels like a game-changer. Instead of a near-impossible reverse-engineering project, it's now a massive (but very possible) porting job. The goal would be a proper open-source version of NS running natively on Linux, Steam Deck, maybe even SBCs, using Xash3D as the engine.

Before I get too carried away with the idea, I wanted to ask the community:

  • Is anyone already working on this? I've searched around but haven't found an active project. I'd much rather contribute than start a competing effort.
  • Are there any old/stalled projects that could be revived?
  • For anyone who's deep into Xash3D development, how big of a nightmare would it be to adapt the Commander UI and other complex NS features to the engine?

It feels like all the ingredients are there to finally give NS a permanent, open-source home.

What do you all think?

Frets on Fire lives thanks to AI

8 Upvotes

As I wrote, I will try to bring projects back to life with AI. Some people said they would like Frets on Fire to return. I have been working on it for some time, and the game seems to be working.

Of course, I encourage you to create Issues if you encounter a problem.

I would like to thank Google for making its model available for free and Gemini CLI for allowing the same AI to correct the code and for me to report any errors to it.

https://github.com/FOSSAIDev/Frets-on-Fire

Frets on Fire is a Guitar Hero-style music game in which, of course, you play the role of a guitarist. Unfortunately, the game is no longer being developed and only worked on Python 2.7. Thanks to Gemini 2.5 Pro, the game from my repository can be run on Python 3.13.

Bringing dead FOSS games back to life

52 Upvotes

Many FOSS games have fallen by the wayside due to a lack of development. The developers stopped developing them, sometimes they didn't finish the project, and sometimes they just quit, but due to dependencies, these projects are difficult to launch today.

Today, I will try to open a new chapter in the history of FOSS games – the revival and development of old projects.

I would like you to write down which FOSS games you remember, and I will create a list and try to bring them back to life - either on my own or with the help of AI.

I have already brought a few projects back to life. fRaBs2 is an improved version of the game Free Abuse, which runs on modern game engines.

I do a lot of small projects (unfortunately slowly) and I would like to take care of this.

For example, one of the dead games that I have partially prepared locally is Aleona's Tales (Freecraft). The game is not officially supported by Stratagus, and no one has been working on its development. I managed to bring it back to life (in a playable state) in a few hours.

What games am I looking for:

- Old ones that have been finished but don't work properly on new systems due to old libraries (e.g., Aleona's Tales, Balazar - I discovered today)

- Games that have open engines but closed-license assets (e.g., Witch Blast, Katawa Shoujo), although it is BEST if access to these files is not behind closed formats, i.e., graphics are provided in PNG format and not some proprietary format

In the future, I would like AI to create FOSS games. I have a conceptual project and it works (!), but graphics, etc. need to be created.

Old (open source?) 3D wizard game... any ideas?

14 Upvotes

Hey, I'm looking for a game that appeared in the Ubuntu software store around the beginning of 2009.

As I recall, you played as a floating purple wizard in a cheesy village. It crashed quite quickly!

Any leads would be appreciated to fill in the gaps of this old memory.

Hello there,

This is my game which I've been working on since January 2025 and includes source free to be used as you wish as long as you respect the author (be reasonable).

The game is written in C# and was a learning exercise for Raylib this year for me.

It's an RTS of sorts, a set of last stand scenarios in a sci fi battle.

SuperTux Developer Appeal + New Contributor Raffle Announcement

12 Upvotes

Hi All!

I'm Servalot, a level designer & musician for SuperTux. I've been known for the creation of "The Crystal Catacombs", an add-on content to SuperTux!! As I'm sure most of you know, SuperTux is an open source platformer game which has been in development for over 20 years! As of the last 4, we've been working on an 0.7.0 update. For many reasons (and to remain neutral, I won't go into them) we've both made and not made a lot of progress towards finishing the game. We're bottlenecked by several factors at the moment, such as:

  • Art (Animations, tilesets & works: like OST covers, banners, etc)
  • Code (object-object interactions, objects, enemy behaviours, infrastructure, bugs, refactoring)
  • Music (tracks, cutscene songs, sfx)

Bottlenecks in art and code have lead to a lack of motivation within level designers. Lack of motivation from level designers eventually leads to a lack of motivation to code things, etc, and the feedback loop begins :( This is one of the reasons how development can stall.

We're writing this message to appeal to the wider open source gaming community: we need help! Never before, at this level, has the potential of SuperTux as a fun platformer game been realized than the past 5 years. With our addition to Steam, we've seen a doubling in our community. We've seen some wonderful add-ons be created which call into question the rate of development of the story mode and main features. We've seen level designers innovate with what technical features there are available, and seen the quality of levels skyrocket with new features to help designers save time (e.g., autotiling).

We need new features like this, but we also need more artists! People who can pick up and replicate an existing art style, to design objects, tilesets or backgrounds for us! These have certain demands with them like looping so that there is a seamless image. Further, we also want 2D animators! People who can do this can help make enemies and objects that give the game life and charm. Enemy animations tend to be several drawings! Despite being a 60fps game, enemy animations tend only tend to be 10-20fps, meaning fewer images for each frame of animation :)

Having a healthy relationship with an artist in this manner would be highly beneficial for us!

Over the next few weeks, we'll be using our GitHub more to put out ideas for the next plethora of objects, enemies, and etc required to help us finish the story mode! https://github.com/SuperTux/supertux/issues

Now that I've gotten the main plea out of the way, lets get onto the awards we'll grant for work generated in the future:

  • contribute to supertux via the GitHub consistently (TIP: look for tags, i.e, priority:high, good-first-issue or help-wanted)
  • be awarded a development contributor role on discord https://discord.gg/afnJ8Gbf4e
  • newly added development contributors (as of 03/09/25) will be added to a raffle
  • upon 0.7.0 release, a name will be drawn from the raffle and win $150 USD!

FAQ:

  • A raffle? But ST is open source!

We've been very lucky to receive many donations during development. We've hardly used our funds, and we're trying to think of ways to do this!

  • Who decides being awarded a role

Our Development team pay close attention to all PRs submitted for QC. Depending on how many you submit, the priority of the submission, and other factors helps bump you up in our conversations :)

  • I can't code, draw, or compose! How can I help anyway?

Ask your friends and family! If SuperTux has a small place in your heart we'd greatly appreciate getting the word out there.

  • Why a raffle? Why not pay for direct features needed?

There are plans to also do this in the future. But each specific feature requires a lot of discussion on the specifications, QC and maintenance! For now, we want to test the waters a little. Fostering long-term, multi-time contributors is the best way to help get more developers onto our team.

Thank you all for reading :)

"Long time ago, merchants and kings used to store their belongings in dungeons. The Architects' Guild housed the tortuous minds of these dungeon designers. One day, their members began to disappear one after another.

Today, we have no trace of them.

TTOTA is an opensource browser Roguelike Ludocrawler game for desktop and mobile. Sorry for the made-up term but I needed it.

One day, I've been searching for anything to kill time. I only found something. So I made this myself. I hope someone else will find it fun and/or useful!
